just worked on it today, including uhmw tape, pics will follow...
i think it was well worth the hassle (anti chafe tape special order item from spruce and international shipping $$), but the result is excellent.
it was a multi step process... first the cutouts according to the template. then prepping the angles and handles. then priming everything. then painted the handles in a "caution" yellow with rattle can paint, for better look and feel added another layer of glossy clear coat on the handles, rattle can as well.
of course spread over several building session to allow it to dry.
put a layer of uhmw tape on each of the 2 angle inside faces.
then temporary assembly, had to enlargen the sideskin cutouts to allow for the added thickness from the paint process / keep the skin from scratching.
only then drilled the angles to the skin.
result is super smooth in operation and looking great. will paint the angles when installed. the "caution" yellow gives a nice contrast to the darkish blue theme we have otherwise going.
